2. Description of Related Art

Nerve Growth Factor (NGF) (also known as beta nerve growth factor(Beta-NGF)) is produced as a mature protein of 222 amino acids inlength, following cleavage of a 18 amino acid signal peptide. The geneencoding NGF is located on chromosome 1p13.1. A biologically active formof NGF is a secreted protein which homodimerizes and is incorporatedinto a larger complex. NGF is a member of the neurotrophins (NTs), whichare a group of structurally-related proteins further includingbrain-derived neurotrophic factor (BDNF), NT-3, and NT-4/5. (Wyman etal., Gene Therapy (1999), 6:1648-1660). NTs support the survival ofspecific types of neurons and neurotransmitter systems, being producedby cells that are targeted by innervating neurons. Id. Basal forebrain,substantia nigra, brain stem, cortex, and spinal cord are nervous systemregions having demonstrated responsiveness to NGF. Id.

All NTs bind to a low-affinity receptor identified as p75. (Sarchielliet al., Expert Rev. Neurotherapeutics (2004), 4(1):115-127). NGFselectively binds to, and displays a high affinity for, the highaffinity neurotrophin receptor TrkA. Id. It has recently beendemonstrated that NGF acts through its low-affinity receptor p75 in adevelopmentally-regulated signaling pathway necessary for myogenicdifferentiation and muscle repair in vivo. (Deponti et al., Mol. Biol.Cell (2009), 20:3620-3627).

NGF has also been demonstrated to interact with pain-signalling systemsin adult animals, and is responsible for hyperalgesia when administeredeither locally or systemically in many species. (Sarchielli et al.,Expert Rev. Neurotherapeutics (2004), 4(1):115-127). NGF has been shownto induce a pain-like response when infused into the CSF in rats, andhas been demonstrated to maintain chronic pain. Furthermore, NGF hasbeen demonstrated to contribute to the development of mechanicalallodynia occurring 8-12 hours later, and to the secondary painresponse. Id.

Pain may often be addressed through the administration of certainnarcotics or non-steroidal anti-inflammatory drugs (NSAIDs). However,the administration of these treatments may occur at the cost of certainnegative consequences. NSAIDs have the potential to cause kidneyfailure, intestinal bleeding, and liver dysfunction. Narcotics have thepotential to cause nausea, vomiting, impaired mental functioning, andaddiction. Therefore, it is desirable to identify alternative treatmentsfor pain in order to avoid certain of these negative consequences.

NGF is believed to play a role in a multitude of diseases and disorders,including but not limited to pain associated with a broad range ofdiseases and disorders, such as pain associated with cancers,neuropathic pain, and neurogenic pain. Due to the perceived involvementof NGF in a wide range of pain-related diseases and disorders, thereremains a need in the art for compositions and methods useful forpreventing or treating diseases and disorders associated with NGF, andparticularly those associated with pain. Particularly preferred anti-NGFcompositions are those having minimal or minimizing adverse reactions,such as inflammation when administered to the patient. Compositions ormethods that reduce or inhibit diseases or disorders associated withNGF, such as pain, are beneficial to the patient in need thereof.

Another aspect of the invention consists in using the capacity of an NGFantagonist according to the invention, e.g., an antibody or antibodyfragment according to the invention that binds to nerve growth factor(NGF), or another polypeptide, such as a fragment of NGF or TrkA or anucleic acid which selectively inhibits the association of NGF withTrkA, without appreciably inhibiting the association of NGF with p75 tobring relief to the patient suffering from chronic visceral pain. Thesubject NGF antagonists according to the invention, e.g., antibodies orantibody fragments, are capable of inhibiting or blocking the visceralhypersensitivity present in the pathophysiology of visceral functionaldisorders, in the case of chronic pain. Herein, the expression chronicvisceral functional disorders is understood to include by way of exampledisorders of the sensitivity of the viscera having a nervous origin,also known by the name visceralgia. The viscera include the digestive,respiratory and urogenital organs and the endocrine systems, as well asthe spleen, the heart and the large vessels. From the medical point ofview, a chronic visceralgia is characterized by a threshold ofsensitivity to pain which is lowered compared with the normal threshold,in response to external mechanical stimuli. Chronic visceral pain is inaddition characterized by the absence of an inflammatory situationconcomitant with the functional disorders. More specifically, chronicvisceral pain includes the following chronic disorders: chronicdyspepsia, a functional digestion disorder occurring in the absence of adetectable organic lesion and which may be symptomatic of other diseasesor other disorders; chronic dysmenorrhea, characterized by painassociated with menstruation; chronic pancreatitis, which ischaracterized by rapid loss of weight, asthenia, pain at the pancreaticpoint, a jaundice with distension of the gall bladder and digestivedisorders due to pancreatic insufficiency, including hereditary chronicpancreatitis, a dominant autosomally transmitted disease which manifestsitself from childhood by abdominal and recidivous painful attacks andwhich is characterized in adults by signs of insufficiency as well as bycalcifications of the pancreas; chronic gastroesophageal reflux, whichis characterized by a return into the esophagus of the acidic gastriccontent and which causes, generally after a meal, ascending retrosternalburns, sometimes accompanied by acidic regurgitations; IBS (irritablebowel syndrome), which is a non-inflammatory chronic diseasecharacterized by abdominal pain and diarrhea and/or constipation, withno detectable biochemical and histological modification. In addition theinvention provides pharmaceutical compositions suitable for use intreating or preventing said pain indications, preferably for humantherapy, comprising an effective amount of at least one an antibody orantibody fragment specific to NGF according to the invention that bindsto nerve growth factor (NGF), which inhibits the association of NGF withTrkA, without appreciably inhibiting the association of NGF with p75. Asdiscussed infra, these compositions may be administrable by differentroutes and dosage regimens.

The criteria for the diagnosis of IBS are (1) abdominal pain ordiscomfort which is relieved by defecation and which is associated witha modification of the frequency and of the consistency of the stools and(2) an irregular defecation profile characterized by at least three ofthe following phenomena: (a) frequency of the stools affected, (b) formof the stools altered, (c) passing of the stool affected, (d) passing ofmucus, and (e) sensation of abdominal distension.

Chronic visceral pain, in particular gastrointestinal pain, ischaracterized by an abnormal perception of various external stimuli inthe patients or in the animal. This abnormal perception of externalstimuli may be defined as a decrease in the sensitivity threshold of thepatient or of the animal to these external stimuli, compared with acontrol subject. This physiopathological condition in which a stimuluswhich is not painful under normal conditions is perceived as beingpainful and which corresponds to a decrease in the sensitivity thresholdis called allodynia. The administration of a an antibody or antibodyfragment according to the invention to a subject suffering from chronicvisceral pain made it possible to abolish the lowering of thesensitivity threshold of this subject to external stimuli, with a returnto a sensitivity threshold comparable to that observed in a controlhealthy subject. The subject antibodies or fragments according to theinvention may be used for the manufacture of a medicament intended forthe prevention or treatment of chronic visceral pain.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Definitions

It is to be understood that this invention is not limited to theparticular methodology, protocols, cell lines, animal species or genera,and reagents described, as such may vary. It is also to be understoodthat the terminology used herein is for the purpose of describingparticular embodiments only, and is not intended to limit the scope ofthe present invention which will be limited only by the appended claims.As used herein the singular forms “a”, “and”, and “the” include pluralreferents unless the context clearly dictates otherwise. Thus, forexample, reference to “a cell” includes a plurality of such cells andreference to “the protein” includes reference to one or more proteinsand equivalents thereof known to those skilled in the art, and so forth.All technical and scientific terms used herein have the same meaning ascommonly understood to one of ordinary skill in the art to which thisinvention belongs unless clearly indicated otherwise.

Nerve Growth Factor (NGF): As used herein, NGF (also referred to asBeta-NGF; HSAN5; and NGFB) encompasses not only the following matureamino acid sequence available from R&D Systems (Minneapolis, Minn.) asHomo sapiens Beta-Nerve Growth Factor (β-NGF):

ssshpifhrgefsvcdsysvwvgdkttatdikgkevmvlgevninnsvfkqyffetkcrdpnpvdsgcrgidskhwnsycttthtfvkaltmdgkqaawrfiridtacvcvlsrkavrra (SEQ ID NO: 411), butalso any pro-, mature, soluble, and/or membrane-bound forms of this NGFamino acid sequence, as well as mutants (mutiens), splice variants,isoforms, orthologues, homologues and variants of this sequence.

“Nerve Growth Factor antagonist” as used refers to any compound thatantagonizes at least one biological activity elicited by NGF. In thepreferred embodiment the NGF antagonist according to the invention willcomprise an NGF antibody or fragment according to the invention, oranother compound, that binds to nerve growth factor (NGF), and whichinhibits the association of NGF with TrkA, without appreciablyinhibiting the association of NGF with p75. These compounds may includefragments of NGF or TrkA, antisense or silencing RNAs, small moleculesor other compounds identified in suitable binding and/or functionalassays that binds to nerve growth factor (NGF), and which inhibits theassociation of NGF with TrkA, without appreciably inhibiting theassociation of NGF with p75.

“Pain” as used herein refers to pain of any etiology, including acuteand chronic pain, and any pain with an inflammatory component. As usedherein, “pain” includes nociception and the sensation of pain, and paincan be assessed objectively and subjectively, using pain scores andother methods well-known in the art. The pain can be primary orsecondary pain, as is well-known in the art. Deagle's Law of theMultilevel Pain Gate states, “Changes at one level of the multilevelgate cause pathway and molecular neurotransmitter and inflammatorymediator changes at all other levels.” Pain can arise at any level ofthe gating process, with different molecules responsible, and differentgenetic, pharmaceutical, immunopharmaceutical and technical challengesto block the gate mediators. Pain of all types arises through themultilevel gate, with changes in molecular upregulation at all othercontinuous levels. Thus levels of molecules that open the gate in theskin are increased in fibromyalgia and skin levels of cytokines andexcitatory neurotransmitters are increased in the brain and skin inspinal cord and peripheral nerve injuries. Pain is a neurologic signaldisease and may or may not be associated with tissue inflammation. Lackof structural disease or tissue inflammation in conditions such asfibromyalgia or other non-inflammatory pain disorders such asnon-inflammatory neuropathy, are primarily due to molecular increasedpain signal transmission. Irrespective of the type of pain, whether itis acute pain as in a sprain, sports injury or jellyfish sting, orwhether it is chronic pain as in arthritis, migraine pain, back or neckpain from herniated disks, RSD/CRPS pain, migraine, fibromyalgia,interstitial cystitis, neuropathic pain, post-stroke pain, etc., theunderlying basis is the opening of the pain gate to allow thetransmission of the pain signal from the primary or higher gates to thecortex at gate levels six and seven, where higher receptive, motor andbehavioral responses occur. This model differs substantially from themodel that inflammation is the sole cause of pain and that othermolecular modulators of pain signal transmission or inhibition are notprimary in the cause of chronic or acute pain disorders. Infibromyalgia, non-inflammatory neuromodulatory molecules are increasedin the skin as well as in other disorders at the pain gates inflammatorymolecules and profacilatory pain signal modulators are increased.Receptor density on the nerve fibers increases due to increased nervetraffic transmitting painful stimuli. Blockade of faciliativeneurotransmitters and inflammatory gate controlling molecules narrowsthe twelve-lane superhighway facilitated for pain in the chronic painstate down to a two lane normal pathway, and reduces the receptordensity for neurotransmitters as well.

This process involves pain gate facilitatory molecules. In other tissuesand circumstances, these may be proinflammatory, or neutral, oranti-inflammatory. Irrespective of the characteristic of the pain,whether it is sharp, dull, aching, burning, stabbing, numbing ortingling, all pain arises with the allowance of increased signal of painat one of the seven pain gate levels at the specific site of thestructures that comprise the gates. In the skin this structure is theLangerhans dermal structures, next the dorsal root ganglion, the dorsalhorn substantia gelatinosa, ascending spinothalamic tracts, subthalamicnuclei, sensory receptive cortex, and anterior motor and behavioralresponse cortex. Pain gate facilatatory molecules such as in thecondition of fibromyalgia can be identified in the skin with increasedfrequency in this condition. Lack of pain gate inhibitory molecules mayalso be identified at all seven levels of the gate, with upregulation ofgenes, proteins, enzymes and glial cell transformation to open the gatein pain and down-regulation of genes, proteins, enzymes and blockade ofglial cell transformation molecules in the pain state. Thus pain can beviewed as a signal disease and a neurological informational disorder,with excessive transmission to higher levels from one gate to anothergate of pain signal increasingly processed, with lack of signalinhibition until there is a cortical response. According to a study onneuropharmaceutical multilevel neural pain gate andtransduction-transmission blockades, the neural process of pain requiresmultilevel hierarchical integrated gating and requires the pain gate tobe opened by inflammatory molecules. These include interleukin 1 Beta,IL1B; necrosis factor alpha, TNF-Alpha; interleukin 6, IL-6; interleukin8, IL-8; interleukin 2, IL-2; and vanilloid receptor 1, VR1; andgranulocyte inhibitor factor, GIF; iNO, glial cell activation, and freeradical molecules such as hydroxyl OH, and nitric oxide or nitroperoxylradicals NO, and NOOH. These may be blocked with pharmaceuticals thatbind to the receptor.

Pain may be present in inflammatory or non-inflammatory conditions andtherefore the presence of molecules that are found to cause or propagatepain if these molecules are not found at the pain gate. Non-inflammatoryconditions such as fibromyalgia, myofascial pain, and non-inflammatorymetabolic neuritic pain syndromes are excellent examples.

For example, “pain associated with chronic prostatitis and/or chronicpelvic pain syndrome” as used herein refers to lower abdominal (pelvic)pain; lower stomach pain; bladder pain; suprapubic pain; pain in thepenis, testicles, scrotum and perineum; urethral pain; dyspareunia;pain, pressure or discomfort that may increase as the bladder fills;dysuria; and ejaculatory pain.

Although analgesia in the strictest sense is an absence of pain, as usedherein, “analgesia” refers to reduction in pain perceived by anindividual.

“Analgesia agent”, “analgesic agent” or “analgesic” refers to anybiomolecule, drug or active agent that alleviates or prevents pain. Thisincludes in particular the subject NGF antibodies and fragments as wellas other actives such as opioids and NSAIDs.

“Acute pain” refers to sudden pain from a specific cause (injury,infection, inflammation, etc.) that has lasted for a limited period oftime (as opposed to chronic pain).

“Chronic pain” refers to a persistent state of pain. Chronic pain isoften associated with long-term incurable or intractable medicalconditions or diseases.

“Procedural pain” refers to pain arising from a medical, dental surgicalor other procedure wherein the procedure may be planned or associatedwith acute trauma.

“Headache disorder” includes migraine, tension headache, clusterheadache, trigeminal neuralgia, secondary headaches, andmiscellaneous-type headaches.

“Migraine” includes migraine headache, migraine without aura, migrainewith aura, and migraine with aura but without headache.

“Systemic side effects” sometimes associated with pain include, but arenot limited to, cardiovascular including peripheral vasodilatation andinhibition of baroreceptors; dermatologic including pruritus (itching),flushing and red eyes; gastrointestinal including nausea and vomiting,decreased gastric motility, decreased biliary, pancreatic and intestinalsecretions and delays in food digestion, diminished peristaltic waves inlarge intestine contributing to constipation, epigastric distress orbiliary colic in biliary tract; respiratory including depressedrespiratory effort; and urinary including urinary urgency and difficultywith urination; and peripheral limb heaviness.

“Central nervous system side effects” or “CNS side effects” associatedwith pain sometimes include, but are not limited to, narcosis, euphoria,drowsiness, apathy, psychotic ideation, mental confusion, alteration inmood, reduction in body temperature, feelings of relaxation, dysphoria(an emotional state characterized by anxiety, depression, or unease),and nausea and vomiting (caused by direct stimulation of chemoreceptorsin the medulla).

As used herein, “treatment” is an approach for obtaining beneficial ordesired clinical results. For purposes of this invention, beneficial ordesired clinical results include, but are not limited to, one or more ofthe following: improvement or alleviation of any aspect of pain,including acute, chronic, inflammatory, neuropathic, or post-surgicalpain. For purposes of this invention, beneficial or desired clinicalresults include, but are not limited to, one or more of the following:including lessening severity, alleviation of one or more symptomsassociated with pain including any aspect of pain (such as shorteningduration of pain, and/or reduction of pain sensitivity or sensation).

“Reducing incidence” of pain means any of reducing severity (which caninclude reducing need for and/or amount of (e.g., exposure to) otherdrugs and/or therapies generally used for this conditions), duration,and/or frequency (including, for example, delaying or increasing time topain in an individual). As is understood by those skilled in the art,individuals may vary in terms of their response to treatment, and, assuch, for example, a “method of reducing incidence of pain in anindividual” reflects administering the NGF antibodies or fragmentsdescribed herein alone or in association with another active such as anNSAID or opioid as described herein, based on a reasonable expectationthat such administration may likely cause such a reduction in incidencein that particular individual.

“Ameliorating” pain or one or more symptoms of pain means a lessening orimprovement of one or more symptoms of a pain as compared to notadministering an NGF antibody or fragment alone or in association withanother active agonist such as an NSAID or opioid.

“Ameliorating” also includes shortening or reduction in duration of asymptom.

“Palliating” pain or one or more symptoms of pain means lessening theextent of one or more undesirable clinical manifestations of pain in anindividual or population of individuals treated with an NGF antibody orfragment in accordance with the invention.

As used therein, “delaying” the development of pain means to defer,hinder, slow, retard, stabilize, and/or postpone progression of pain.This delay can be of varying lengths of time, depending on the historyof the disease and/or individuals being treated. As is evident to oneskilled in the art, a sufficient or significant delay can, in effect,encompass prevention, in that the individual does not develop pain. Amethod that “delays” development of the symptom is a method that reducesprobability of developing the symptom in a given time frame and/orreduces extent of the symptoms in a given time frame, when compared tonot using the method. Such comparisons are typically based on clinicalstudies, using a statistically significant number of subjects.

For example, palliating” bone cancer pain (such as cancer painassociated with bone metastasis) or one or more symptoms of a bonecancer pain means lessening the extent of one or more undesirableclinical manifestations of bone cancer pain in an individual orpopulation of individuals treated with an NGF antibody or fragment inaccordance with the invention.

As used therein, “delaying” the development of pain, e.g., bone cancerpain including cancer pain associated with bone metastasis means todefer, hinder, slow, retard, stabilize, and/or postpone progression ofbone cancer pain including cancer pain associated with bone metastasis.This delay can be of varying lengths of time, depending on the historyof the disease and/or individuals being treated. As is evident to oneskilled in the art, a sufficient or significant delay can, in effect,encompass prevention, in that the individual does not develop bonecancer pain including cancer pain associated with bone metastasis. Amethod that “delays” development of the symptom is a method that reducesprobability of developing the symptom in a given time frame and/orreduces extent of the symptoms in a given time frame, when compared tonot using the method. Such comparisons are typically based on clinicalstudies, using a number of subjects sufficient to give a statisticallysignificant result.

“Development” or “progression” of pain, e.g., bone cancer pain includingcancer pain associated with bone metastasis means initial manifestationsand/or ensuing progression of the pain related disorder. Development ofbone cancer pain including cancer pain associated with bone metastasiscan be detectable and assessed using standard clinical techniques aswell known in the art. However, development also refers to progressionthat may be undetectable. For purpose of this invention, development orprogression refers to the biological course of the symptoms.

“Development” includes occurrence, recurrence, and onset. As used herein“onset” or “occurrence” of pain, e.g., bone cancer pain (such as cancerpain associated with bone metastasis) includes initial onset and/orrecurrence.

As used herein, “co-administration” includes simultaneous administrationand/or administration at different times. Co-administration alsoencompasses administration as a co-formulation (i.e., the NGF antibodyor fragment and another agent are present in the same composition) oradministration as separate compositions. As used herein,co-administration is meant to encompass any circumstance wherein anagent and NGF antibody or fragment are administered to an individual,which can occur simultaneously and/or separately. As further discussedherein, it is understood that the NGF antibody or fragment and an agentcan be administered at different dosing frequencies or intervals. Forexample, an anti-NGF antibody can be administered weekly, while theagent can be administered more frequently. It is understood that the NGFantagonist and the agent can be administered using the same route ofadministration or different routes of administration. Preferably theanti-NGF antibody or fragment is one that elicits an effective analgesicresponse alone, i.e., palliates or prevents pain in subjects where thisis needed. Such conditions are identified infra and include anycondition where pain is to be alleviated or prevented by antagonizingNGF, e.g., via the interaction of NGF with TrkA while not appreciablyaffecting the interaction of NGF with p75. These conditions include inparticular conditions involving acute and/or chronic pain such asassociated with cancer, rheumatoid arthritis, migraine, and the like.

The term “opioid analgesic” refers to all drugs, natural or synthetic,with morphine-like actions. The synthetic and semi-synthetic opioidanalgesics are derivatives of five chemical classes of compound:phenanthrenes; phenylheptylamines; phenylpiperidines; morphinans; andbenzomorphans, all of which are within the scope of the term. Exemplaryopioid analgesics include codeine, dihydrocodeine, diacetylmorphine,hydrocodone, hydromorphone, levorphanol, oxymorphone, alfentanil,buprenorphine, butorphanol, fentanyl, sufentanyl, meperidine, methadone,nalbuphine, propoxyphene and pentazocine or pharmaceutically acceptablesalts thereof.

The term “NSAID” refers to a non-steroidal anti-inflammatory compound.NSAIDs are categorized by virtue of their ability to inhibitcyclooxygenase. Cyclooxygenase 1 and cyclooxygenase 2 are two majorisoforms of cyclooxygenase and most standard NSAIDs are mixed inhibitorsof the two isoforms. Most standard NSAIDs fall within one of thefollowing five structural categories: (1) propionic acid derivatives,such as ibuprofen, naproxen, naprosyn, diclofenac, and ketoprofen; (2)acetic acid derivatives, such as tolmetin and slindac; (3) fenamic acidderivatives, such as mefenamic acid and meclofenamic acid; (4)biphenylcarboxylic acid derivatives, such as diflunisal and flufenisal;and (5) oxicams, such as piroxim, sudoxicam, and isoxicam. Another classof NSAID has been described which selectively inhibit cyclooxygenase 2.Cox-2 inhibitors have been described, e.g., in U.S. Pat. Nos. 5,616,601;5,604,260; 5,593,994; 5,550,142; 5,536,752; 5,521,213; 5,475,995;5,639,780; 5,604,253; 5,552,422; 5,510,368; 5,436,265; 5,409,944; and5,130,311, all of which are hereby incorporated by reference. Certainexemplary COX-2 inhibitors include celecoxib (SC-58635), DUP-697,flosulide (CGP-28238), meloxicam, 6-methoxy-2 naphthylacetic acid(6-MNA), rofecoxib, MK-966, nabumetone (prodrug for 6-MNA), nimesulide,NS-398, SC-5766, SC-58215, T-614; or combinations thereof.

In some embodiments, aspirin and/or acetominophen are taken inconjunction with NGF antibody or fragment. Aspirin is another type ofnon-steroidal anti-inflammatory compound.

“Host cell” herein refers to any cell, e.g., a bacterial, yeast,mammalian, avian, plant or insect cell that contains and/or expresses anNGF antagonist according to the invention, e.g., an NGF antibody orfragment thereof as disclosed herein. In the exemplary embodiment thehost cell is a mating competent yeast cell.

“Transgenic animal or plant” refers to a non-human animal or a plantwhich is genetically engineered to introduce or delete a specific geneor gene sequence. Herein this typically refers to a non-human animalsuch as a rodent, bovine, or a plant engineered to express a NGFantagonist according to the invention, e.g., an antibody or antibodyfragment that specifically binds NGF and preferably one that antagonizesthe interaction of NGF with TrkA and which does not appreciably affectthe interaction of NGF with p75, or alternatively is an antibody orantibody fragment that specifically binds NGF and is one thatantagonizes the interaction of NGF with TrkA and the interaction of NGFwith p75. expr

Mating competent yeast species: In the present invention this isintended to broadly encompass any diploid or tetraploid yeast which canbe grown in culture. Such species of yeast may exist in a haploid,diploid, or other polyploid form. The cells of a given ploidy may, underappropriate conditions, proliferate for an indefinite number ofgenerations in that form. Diploid cells can also sporulate to formhaploid cells. Sequential mating can result in tetraploid strainsthrough further mating or fusion of diploid strains. The presentinvention contemplates the use of haploid yeast, as well as diploid orother polyploid yeast cells produced, for example, by mating orspheroplast fusion.

In one embodiment of the invention, the mating competent yeast is amember of the Saccharomycetaceae family, which includes the generaArxiozyma; Ascobotryozyma; Citeromyces; Debaryomyces; Dekkera;Eremothecium; Issatchenkia; Kazachstania; Kluyveromyces; Kodamaea;Lodderomyces; Pachysolen; Pichia; Saccharomyces; Saturnispora;Tetrapisispora; Torulaspora; Williopsis; and Zygosaccharomyces. Othertypes of yeast potentially useful in the invention include Yarrowia;Rhodosporidium; Candida; Hansenula; Filobasium; Sporidiobolus; Bullera;Leucosporidium and Filobasidella.

In a preferred embodiment of the invention, the mating competent yeastis a member of the genus Pichia. In a further preferred embodiment ofthe invention, the mating competent yeast of the genus Pichia is one ofthe following species: Pichia pastoris, Pichia methanolica, andHansenula polymorpha (Pichia angusta). In a particularly preferredembodiment of the invention, the mating competent yeast of the genusPichia is the species Pichia pastoris. In an even more preferredembodiment expression will be effected using the diploid expressionsystem disclosed in U.S. Pat. No. 7,927,863, issued on Apr. 19, 2011,assigned to Alder Biopharmaceuticals and the Keck Graduate Institute.

Selectable Marker: A selectable marker is a gene or gene fragment thatconfers a growth phenotype (physical growth characteristic) on a cellreceiving that gene as, for example through a transformation event. Theselectable marker allows that cell to survive and grow in a selectivegrowth medium under conditions in which cells that do not receive thatselectable marker gene cannot grow. Selectable marker genes generallyfall into several types, including positive selectable marker genes suchas a gene that confers on a cell resistance to an antibiotic or otherdrug, temperature when two ts mutants are crossed or a ts mutant istransformed; negative selectable marker genes such as a biosyntheticgene that confers on a cell the ability to grow in a medium without aspecific nutrient needed by all cells that do not have that biosyntheticgene, or a mutagenized biosynthetic gene that confers on a cellinability to grow by cells that do not have the wild type gene; and thelike. Suitable markers include but are not limited to: ZEO; G418; LYS3;MET1; MET3a; ADEl; ADE3; URA3; and the like.

Expression Vector: These DNA vectors contain elements that facilitatemanipulation for the expression of a foreign protein within the targethost cell. Often, manipulation of sequences and production of DNA fortransformation is first performed in a bacterial host, e.g. E. coli, andusually vectors will include sequences to facilitate such manipulations,including a bacterial origin of replication and appropriate bacterialselection marker. Selection markers encode proteins necessary for thesurvival or growth of transformed host cells grown in a selectiveculture medium. Host cells not transformed with the vector containingthe selection gene will not survive in the culture medium. Typicalselection genes encode proteins that (a) confer resistance toantibiotics or other toxins, (b) complement auxotrophic deficiencies, or(c) supply critical nutrients not available from complex media.Exemplary vectors and methods for transformation of yeast are described,for example, in Burke, D., Dawson, D., & Stearns, T. (2000). Methods inyeast genetics: a Cold Spring Harbor Laboratory course manual.Plainview, N.Y.: Cold Spring Harbor Laboratory Press.

Expression vectors for use in the methods of the invention will furthertypically include host cell specific sequences, including a selectableauxotrophic or drug marker for identifying transformed host cells, e.g.,yeast strains. A drug marker may further be used to amplify copy numberof the vector in a host cell or in a transgenic animal.

The polypeptide coding sequence of interest is operably linked totranscriptional and translational regulatory sequences that provide forexpression of the polypeptide in yeast cells. These vector componentsmay include, but are not limited to, one or more of the following: anenhancer element, a promoter, and a transcription termination sequence.Sequences for the secretion of the polypeptide may also be included,e.g. a signal sequence, and the like. A host specific origin ofreplication is optional, as expression vectors are often integrated intothe host cell genome. In one embodiment of the invention, thepolypeptide of interest is operably linked, or fused, to sequencesproviding for optimized secretion of the polypeptide from host cells.

Nucleic acids are “operably linked” when placed into a functionalrelationship with another nucleic acid sequence. For example, DNA for asignal sequence is operably linked to DNA for a polypeptide if it isexpressed as a preprotein that participates in the secretion of thepolypeptide; a promoter or enhancer is operably linked to a codingsequence if it affects the transcription of the sequence. Generally,“operably linked” means that the DNA sequences being linked arecontiguous, and, in the case of a secretory leader, contiguous and inreading frame. However, enhancers do not have to be contiguous. Linkingis accomplished by ligation at convenient restriction sites oralternatively via a PCR/recombination method familiar to those skilledin the art (GatewayR Technology; Invitrogen, Carlsbad Calif.). If suchsites do not exist, the synthetic oligonucleotide adapters or linkersare used in accordance with conventional practice.

Promoters are untranslated sequences located upstream (5′) to the startcodon of a structural gene (generally within about 100 to 1000 bp) thatcontrol the transcription and translation of particular nucleic acidsequences to which they are operably linked. Such promoters fall intoseveral classes: inducible, constitutive, and repressible promoters(that increase levels of transcription in response to absence of arepressor). Inducible promoters may initiate increased levels oftranscription from DNA under their control in response to some change inculture conditions, e.g., the presence or absence of a nutrient or achange in temperature.

The promoter fragment may also serve as the site for homologousrecombination and integration of the expression vector into the samesite in the host cell genome; alternatively a selectable marker is usedas the site for homologous recombination.

The inventive antibody polypeptides of interest may be producedrecombinantly not only directly, but also as a fusion polypeptide with aheterologous polypeptide, e.g. a signal sequence or other polypeptidehaving a specific cleavage site at the N-terminus of the mature proteinor polypeptide. In general, the signal sequence may be a component ofthe vector, or it may be a part of the polypeptide coding sequence thatis inserted into the vector. The heterologous signal sequence selectedpreferably is one that is recognized and processed through one of thestandard pathways available within the host cell. The S. cerevisiaealpha factor pre-pro signal has proven effective in the secretion of avariety of recombinant proteins from P. pastoris. Other yeast signalsequences include the alpha mating factor signal sequence, the invertasesignal sequence, and signal sequences derived from other secreted yeastpolypeptides. Additionally, these signal peptide sequences may beengineered to provide for enhanced secretion in the chosen expressionsystems. Other secretion signals of interest also include mammaliansignal sequences, which may be heterologous to the protein beingsecreted, or may be a native sequence for the protein being secreted.Signal sequences include pre-peptide sequences, and in some instancesmay include propeptide sequences. Many such signal sequences are knownin the art, including the signal sequences found on immunoglobulinchains, e.g., K28 preprotoxin sequence, PHA-E, FACE, human MCP-1, humanserum albumin signal sequences, human Ig heavy chain, human Ig lightchain, and the like. For example, see Hashimoto et. al. Protein Eng11(2) 75 (1998); and Kobayashi et. al. Therapeutic Apheresis 2(4) 257(1998).

Transcription may be increased by inserting a transcriptional activatorsequence into the vector. These activators are cis-acting elements ofDNA, usually about from 10 to 300 bp, which act on a promoter toincrease its transcription. Transcriptional enhancers are relativelyorientation and position independent, having been found 5′ and 3′ to thetranscription unit, within an intron, as well as within the codingsequence itself. The enhancer may be spliced into the expression vectorat a position 5′ or 3′ to the coding sequence, but is preferably locatedat a site 5′ from the promoter.

Expression vectors used in eukaryotic host cells may also containsequences necessary for the termination of transcription and forstabilizing the mRNA. Such sequences are commonly available from 3′ tothe translation termination codon, in untranslated regions of eukaryoticor viral DNAs or cDNAs. These regions contain nucleotide segmentstranscribed as polyadenylated fragments in the untranslated portion ofthe mRNA.

Construction of suitable vectors containing one or more of theabove-listed components employs standard ligation techniques orPCR/recombination methods. Isolated plasmids or DNA fragments arecleaved, tailored, and re-ligated in the form desired to generate theplasmids required or via recombination methods. For analysis to confirmcorrect sequences in plasmids constructed, the ligation mixtures areused to transform host cells, and successful transformants selected byantibiotic resistance (e.g. ampicillin or Zeocin) where appropriate.Plasmids from the transformants are prepared, analyzed by restrictionendonuclease digestion and/or sequenced.

As an alternative to restriction and ligation of fragments,recombination methods based on att sites and recombination enzymes maybe used to insert DNA sequences into a vector. Such methods aredescribed, for example, by Landy (1989) Ann. Rev. Biochem. 58:913-949;and are known to those of skill in the art. Such methods utilizeintermolecular DNA recombination that is mediated by a mixture of lambdaand E. coli-encoded recombination proteins. Recombination occurs betweenspecific attachment (att) sites on the interacting DNA molecules. For adescription of att sites see Weisberg and Landy (1983) Site-SpecificRecombination in Phage Lambda, in Lambda II, Weisberg, ed. (Cold SpringHarbor, N.Y.: Cold Spring Harbor Press), pp. 211-250. The DNA segmentsflanking the recombination sites are switched, such that afterrecombination, the att sites are hybrid sequences comprised of sequencesdonated by each parental vector. The recombination can occur betweenDNAs of any topology.

Att sites may be introduced into a sequence of interest by ligating thesequence of interest into an appropriate vector; generating a PCRproduct containing att B sites through the use of specific primers;generating a cDNA library cloned into an appropriate vector containingatt sites; and the like.

Folding, as used herein, refers to the three-dimensional structure ofpolypeptides and proteins, where interactions between amino acidresidues act to stabilize the structure. While non-covalent interactionsare important in determining structure, usually the proteins of interestwill have intra- and/or intermolecular covalent disulfide bonds formedby two cysteine residues. For naturally occurring proteins andpolypeptides or derivatives and variants thereof, the proper folding istypically the arrangement that results in optimal biological activity,and can conveniently be monitored by assays for activity, e.g. ligandbinding, enzymatic activity, etc.

In some instances, for example where the desired product is of syntheticorigin, assays based on biological activity will be less meaningful. Theproper folding of such molecules may be determined on the basis ofphysical properties, energetic considerations, modeling studies, and thelike.

The expression host may be further modified by the introduction ofsequences encoding one or more enzymes that enhance folding anddisulfide bond formation, i.e. foldases, chaperonins, etc. Suchsequences may be constitutively or inducibly expressed in the yeast hostcell, using vectors, markers, etc. as known in the art. Preferably thesequences, including transcriptional regulatory elements sufficient forthe desired pattern of expression, are stably integrated in the yeastgenome through a targeted methodology.

For example, the eukaryotic PDI is not only an efficient catalyst ofprotein cysteine oxidation and disulfide bond isomerization, but alsoexhibits chaperone activity. Co-expression of PDI can facilitate theproduction of active proteins having multiple disulfide bonds. Also ofinterest is the expression of BIP (immunoglobulin heavy chain bindingprotein); cyclophilin; and the like. In one embodiment of the invention,each of the haploid parental strains expresses a distinct foldingenzyme, e.g. one strain may express BIP, and the other strain mayexpress PDI or combinations thereof.

The terms “desired protein” or “desired antibody” are usedinterchangeably and refer generally to a NGF antagonist polypeptide,e.g., a parent antibody specific to a target, i.e., NGF or a chimeric orhumanized antibody or a binding portion thereof derived therefrom asdescribed herein. In some instances the NGF antagonist may be a moiety,e.g., a polypeptide or nucleic acid that selectively antagonizes theinteraction of NGF with TrkA while not appreciably affecting theinteraction of NGF with p75. Examples thereof include fragments of NGF,TrkA, small molecules, nucleic acids, and the like which may beidentified in appropriate screening assays, e.g., NGF binding assays,including competitive binding assays.

The term “antibody” is intended to include any polypeptidechain-containing molecular structure with a specific shape that fits toand recognizes an epitope, where one or more non-covalent bindinginteractions stabilize the complex between the molecular structure andthe epitope. This includes intact antibodies and antibody fragments. Thearchetypal antibody molecule is the immunoglobulin, and all types ofimmunoglobulins, IgG, IgM, IgA, IgE, IgD, etc., from all sources, e.g.human, rodent, rabbit, cow, sheep, pig, dog, other mammals, chicken,other avians, etc., are considered to be “antibodies.” A preferredsource for producing antibodies useful as starting material according tothe invention is rabbits. Numerous antibody coding sequences have beendescribed; and others may be raised by methods well-known in the art.Examples thereof include chimeric antibodies, human antibodies and othernon-human mammalian antibodies, humanized antibodies, single chainantibodies (such as scFvs), camelbodies, nanobodies, IgNAR (single-chainantibodies derived from sharks), small-modular immunopharmaceuticals(SMIPs), and antibody fragments such as Fabs, Fab′, F(ab′)₂ and thelike. See Streltsov V A, et al., Structure of a shark IgNAR antibodyvariable domain and modeling of an early-developmental isotype, ProteinSci. 2005 November; 14(11):2901-9.

For example, antibodies or antigen binding fragments may be produced bygenetic engineering. In this technique, as with other methods,antibody-producing cells are sensitized to the desired antigen orimmunogen. The messenger RNA isolated from antibody producing cells isused as a template to make cDNA using PCR amplification. A library ofvectors, each containing one heavy chain gene and one light chain generetaining the initial antigen specificity, is produced by insertion ofappropriate sections of the amplified immunoglobulin cDNA into theexpression vectors. A combinatorial library is constructed by combiningthe heavy chain gene library with the light chain gene library. Thisresults in a library of clones which co-express a heavy and light chain(resembling the Fab fragment or antigen binding fragment of an antibodymolecule). The vectors that carry these genes are co-transfected into ahost cell. When antibody gene synthesis is induced in the transfectedhost, the heavy and light chain proteins self-assemble to produce activeantibodies that can be detected by screening with the antigen orimmunogen.

Antibody coding sequences of interest include those encoded by nativesequences, as well as nucleic acids that, by virtue of the degeneracy ofthe genetic code, are not identical in sequence to the disclosed nucleicacids, and variants thereof. Variant polypeptides can include amino acid(aa) substitutions, additions or deletions. The amino acid substitutionscan be conservative amino acid substitutions or substitutions toeliminate non-essential amino acids, such as to alter a glycosylationsite, or to minimize misfolding by substitution or deletion of one ormore cysteine residues that are not necessary for function. Variants canbe designed so as to retain or have enhanced biological activity of aparticular region of the protein (e.g., a functional domain, catalyticamino acid residues, etc). Variants also include fragments of thepolypeptides disclosed herein, particularly biologically activefragments and/or fragments corresponding to functional domains.Techniques for in vitro mutagenesis of cloned genes are known. Alsoincluded in the subject invention are polypeptides that have beenmodified using ordinary molecular biological techniques so as to improvetheir resistance to proteolytic degradation or to optimize solubilityproperties or to render them more suitable as a therapeutic agent.

Chimeric antibodies may be made by recombinant means by combining thevariable light and heavy chain regions (VL and V_(H)), obtained fromantibody producing cells of one species with the constant light andheavy chain regions from another. Herein chimeric antibodies are alsointended to broadly encompass any antibody that contains amino acidresidues derived from different antibodies, of the same or differentspecies origin. Therefore, chimeric antibodies encompasses humanizedantibodies. Accordingly, in some instances in this application theseterms are used interchangeably. Typically herein chimeric antibodies areobtained by combining non-human variable regions, e.g., rodent or rabbitvariable regions and human constant regions, in order to produce anantibody with predominantly human domains. The production of suchchimeric antibodies is well known in the art, and may be achieved bystandard means (as described, e.g., in U.S. Pat. No. 5,624,659,incorporated herein by reference in its entirety). It is furthercontemplated that the human constant regions of chimeric antibodies ofthe invention may be selected from IgG1, IgG2, IgG3, IgG4, IgG5, IgG6,IgG7, IgG8, IgG9, IgG10, IgG11, IgG12, IgG13, IgG14, IgG15, IgG16,IgG17, IgG18 or IgG19 constant regions.

Humanized antibodies, a species of chimeric antibodies, are antibodiescontaining residues of human and non-human antobody or antibodies, whichtypically are engineered to avoid immunogenicity in a human subject,while retaining desired antibody characteristics such as antigen bindingand in some instances desired antibody effector functions. Typically,humanized antibodies are engineered to contain even more human-likeimmunoglobulin domains, and incorporate the complementarity-determiningregions of the animal-derived antibody and no or few framework residuesfrom the non-human animal antibody. This is accomplished by carefullyexamining the sequence of the hyper-variable loops of the variableregions of the monoclonal antibody, and fitting them to the structure ofthe human antibody chains. Although facially complex, the process isstraightforward in practice. See, e.g., U.S. Pat. No. 6,187,287,incorporated fully herein by reference.

In addition to entire immunoglobulins (or their recombinantcounterparts), immunoglobulin fragments comprising the epitope bindingsite (e.g., Fab′, F(ab′)₂, or other fragments) may be synthesized.“Fragment,” or minimal immunoglobulins may be designed utilizingrecombinant immunoglobulin techniques. For instance “Fv” immunoglobulinsfor use in the present invention may be produced by synthesizing a fusedvariable light chain region and a variable heavy chain region.Combinations of antibodies are also of interest, e.g. diabodies, whichcomprise two distinct Fv specificities. In another embodiment of theinvention, SMIPs (small molecule immunopharmaceuticals), camelbodies,nanobodies, and IgNAR are encompassed by immunoglobulin fragments.

Immunoglobulins and fragments thereof may be modifiedpost-translationally, e.g. to add effector moieties such as chemicallinkers, detectable moieties, such as fluorescent dyes, enzymes, toxins,substrates, bioluminescent materials, radioactive materials,chemiluminescent moieties and the like, or specific binding moieties,such as streptavidin, avidin, or biotin, and the like may be utilized inthe methods and compositions of the present invention. Examples ofadditional effector molecules are provided infra.

A polynucleotide sequence “corresponds” to a polypeptide sequence iftranslation of the polynucleotide sequence in accordance with thegenetic code yields the polypeptide sequence (i.e., the polynucleotidesequence “encodes” the polypeptide sequence), one polynucleotidesequence “corresponds” to another polynucleotide sequence if the twosequences encode the same polypeptide sequence.

A “heterologous” region or domain of a DNA construct is an identifiablesegment of DNA within a larger DNA molecule that is not found inassociation with the larger molecule in nature. Thus, when theheterologous region encodes a mammalian gene, the gene will usually beflanked by DNA that does not flank the mammalian genomic DNA in thegenome of the source organism. Another example of a heterologous regionis a construct where the coding sequence itself is not found in nature(e.g., a cDNA where the genomic coding sequence contains introns, orsynthetic sequences having codons different than the native gene).Allelic variations or naturally-occurring mutational events do not giverise to a heterologous region of DNA as defined herein.

A “coding sequence” is an in-frame sequence of codons that (in view ofthe genetic code) correspond to or encode a protein or peptide sequence.Two coding sequences correspond to each other if the sequences or theircomplementary sequences encode the same amino acid sequences. A codingsequence in association with appropriate regulatory sequences may betranscribed and translated into a polypeptide. A polyadenylation signaland transcription termination sequence will usually be located 3′ to thecoding sequence. A “promoter sequence” is a DNA regulatory regioncapable of binding RNA polymerase in a cell and initiating transcriptionof a downstream (3′ direction) coding sequence. Promoter sequencestypically contain additional sites for binding of regulatory molecules(e.g., transcription factors) which affect the transcription of thecoding sequence. A coding sequence is “under the control” of thepromoter sequence or “operatively linked” to the promoter when RNApolymerase binds the promoter sequence in a cell and transcribes thecoding sequence into mRNA, which is then in turn translated into theprotein encoded by the coding sequence.

Vectors are used to introduce a foreign substance, such as DNA, RNA orprotein, into an organism or host cell. Typical vectors includerecombinant viruses (for polynucleotides) and liposomes (forpolypeptides). A “DNA vector” is a replicon, such as plasmid, phage orcosmid, to which another polynucleotide segment may be attached so as tobring about the replication of the attached segment. An “expressionvector” is a DNA vector which contains regulatory sequences which willdirect polypeptide synthesis by an appropriate host cell. This usuallymeans a promoter to bind RNA polymerase and initiate transcription ofmRNA, as well as ribosome binding sites and initiation signals to directtranslation of the mRNA into a polypeptide(s). Incorporation of apolynucleotide sequence into an expression vector at the proper site andin correct reading frame, followed by transformation of an appropriatehost cell by the vector, enables the production of a polypeptide encodedby said polynucleotide sequence.

“Amplification” of polynucleotide sequences is the in vitro productionof multiple copies of a particular nucleic acid sequence. The amplifiedsequence is usually in the form of DNA. A variety of techniques forcarrying out such amplification are described in a review article by VanBrunt (1990, Bio/Technol., 8(4):291-294). Polymerase chain reaction orPCR is a prototype of nucleic acid amplification, and use of PCR hereinshould be considered exemplary of other suitable amplificationtechniques.

The general structure of antibodies in vertebrates now is wellunderstood (Edelman, G. M., Ann. N.Y. Acad. Sci., 190: 5 (1971)).Antibodies consist of two identical light polypeptide chains ofmolecular weight approximately 23,000 daltons (the “light chain”), andtwo identical heavy chains of molecular weight 53,000-70,000 (the “heavychain”). The four chains are joined by disulfide bonds in a “Y”configuration wherein the light chains bracket the heavy chains startingat the mouth of the “Y” configuration. The “branch” portion of the “Y”configuration is designated the Fab region; the stem portion of the “Y”configuration is designated the Fc region. The amino acid sequenceorientation runs from the N-terminal end at the top of the “Y”configuration to the C-terminal end at the bottom of each chain. TheN-terminal end possesses the variable region having specificity for theantigen that elicited it, and is approximately 100 amino acids inlength, there being slight variations between light and heavy chain andfrom antibody to antibody.

The variable region is linked in each chain to a constant region thatextends the remaining length of the chain and that within a particularclass of antibody does not vary with the specificity of the antibody(i.e., the antigen eliciting it). There are five known major classes ofconstant regions that determine the class of the immunoglobulin molecule(IgG, IgM, IgA, IgD, and IgE corresponding to γ, μ, α, δ, and ε (gamma,mu, alpha, delta, or epsilon) heavy chain constant regions). Theconstant region or class determines subsequent effector function of theantibody, including activation of complement (Kabat, E. A., StructuralConcepts in Immunology and Immunochemistry, 2nd Ed., p. 413-436, Holt,Rinehart, Winston (1976)), and other cellular responses (Andrews, D. W.,et al., Clinical Immunobiology, pp 1-18, W. B. Sanders (1980); Kohl, S.,et al., Immunology, 48: 187 (1983)); while the variable regiondetermines the antigen with which it will react. Light chains areclassified as either κ (kappa) or λ (lambda). Each heavy chain class canbe prepared with either kappa or lambda light chain. The light and heavychains are covalently bonded to each other, and the “tail” portions ofthe two heavy chains are bonded to each other by covalent disulfidelinkages when the immunoglobulins are generated either by hybridomas orby B cells.

The expression “variable region” or “VR” refers to the domains withineach pair of light and heavy chains in an antibody that are involveddirectly in binding the antibody to the antigen. Each heavy chain has atone end a variable domain (V_(H)) followed by a number of constantdomains. Each light chain has a variable domain (V_(L)) at one end and aconstant domain at its other end; the constant domain of the light chainis aligned with the first constant domain of the heavy chain, and thelight chain variable domain is aligned with the variable domain of theheavy chain.

The expressions “complementarity determining region,” “hypervariableregion,” or “CDR” refer to one or more of the hyper-variable orcomplementarity determining regions (CDRs) found in the variable regionsof light or heavy chains of an antibody (See Kabat, E. A. et al.,Sequences of Proteins of Immunological Interest, National Institutes ofHealth, Bethesda, Md., (1987)). These expressions include thehypervariable regions as defined by Kabat et al. (“Sequences of Proteinsof Immunological Interest,” Kabat E., et al., US Dept. of Health andHuman Services, 1983) or the hypervariable loops in 3-dimensionalstructures of antibodies (Chothia and Lesk, J Mol. Biol. 196 901-917(1987)). The CDRs in each chain are held in close proximity by frameworkregions and, with the CDRs from the other chain, contribute to theformation of the antigen binding site. Within the CDRs there are selectamino acids that have been described as the selectivity determiningregions (SDRs) which represent the critical contact residues used by theCDR in the antibody-antigen interaction (Kashmiri, S., Methods, 36:25-34(2005)).

The expressions “framework region” or “FR” refer to one or more of theframework regions within the variable regions of the light and heavychains of an antibody (See Kabat, E. A. et al., Sequences of Proteins ofImmunological Interest, National Institutes of Health, Bethesda, Md.,(1987)). These expressions include those amino acid sequence regionsinterposed between the CDRs within the variable regions of the light andheavy chains of an antibody.

US 2009/0028784 to Garcia-Martinez et al.,the disclosures of each of which are herein incorporated by reference intheir entireties.

Other methods of producing antibodies are well known to those ofordinary skill in the art. For example, methods of producing chimericantibodies are now well known in the art (See, for example, U.S. Pat.No. 4,816,567 to Cabilly et al.; Morrison et al., P.N.A.S. USA,81:8651-55 (1984); Neuberger, M. S. et al., Nature, 314:268-270 (1985);Boulianne, G. L. et al., Nature, 312:643-46 (1984), the disclosures ofeach of which are herein incorporated by reference in their entireties).

Likewise, other methods of producing humanized antibodies are now wellknown in the art (See, for example, U.S. Pat. Nos. 5,530,101, 5,585,089,5,693,762, and 6,180,370 to Queen et al; U.S. Pat.

Antibody polypeptides of the invention having NGF binding specificitymay also be produced by constructing, using conventional techniques wellknown to those of ordinary skill in the art, an expression vectorcontaining an operon and a DNA sequence encoding an antibody heavy chainin which the DNA sequence encoding the CDRs required for antibodyspecificity is derived from a non-human cell source, preferably a rabbitB-cell source, while the DNA sequence encoding the remaining parts ofthe antibody chain is derived from a human cell source.

A second expression vector is produced using the same conventional meanswell known to those of ordinary skill in the art, said expression vectorcontaining an operon and a DNA sequence encoding an antibody light chainin which the DNA sequence encoding the CDRs required for antibodyspecificity is derived from a non-human cell source, preferably a rabbitB-cell source, while the DNA sequence encoding the remaining parts ofthe antibody chain is derived from a human cell source.

The expression vectors are transfected into a host cell by conventiontechniques well known to those of ordinary skill in the art to produce atransfected host cell, said transfected host cell cultured byconventional techniques well known to those of ordinary skill in the artto produce said antibody polypeptides.

The host cell may be co-transfected with the two expression vectorsdescribed above, the first expression vector containing DNA encoding anoperon and a light chain-derived polypeptide and the second vectorcontaining DNA encoding an operon and a heavy chain-derived polypeptide.The two vectors contain different selectable markers, but preferablyachieve substantially equal expression of the heavy and light chainpolypeptides. Alternatively, a single vector may be used, the vectorincluding DNA encoding both the heavy and light chain polypeptides. Thecoding sequences for the heavy and light chains may comprise cDNA,genomic DNA, or both.

The host cells used to express the antibody polypeptides may be either abacterial cell such as E. coli, or a eukaryotic cell. In a particularlypreferred embodiment of the invention, a mammalian cell of awell-defined type for this purpose, such as a myeloma cell, a Chinesehamster ovary (CHO) cell line, a NSO cell line, or a HEK293 cell linemay be used.

The general methods by which the vectors may be constructed,transfection methods required to produce the host cell and culturingmethods required to produce the antibody polypeptides from said hostcells all include conventional techniques. Although preferably the cellline used to produce the antibody is a mammalian cell line, any othersuitable cell line, such as a bacterial cell line such as an E.coli-derived bacterial strain, or a yeast cell line, may alternativelybe used.

Similarly, once produced the antibody polypeptides may be purifiedaccording to standard procedures in the art, such as for examplecross-flow filtration, ammonium sulphate precipitation, affinity columnchromatography and the like.

The antibody polypeptides described herein may also be used for thedesign and synthesis of either peptide or non-peptide mimetics thatwould be useful for the same therapeutic applications as the antibodypolypeptides of the invention.

In one embodiment of the invention, the anti-NGF antibodies of theinvention, or NGF binding fragments thereof, are used to detect thepresence of NGF in a biological sample obtained from a patientexhibiting symptoms of a disease or disorder associated with NGF. Thepresence of NGF, or elevated levels thereof when compared to pre-diseaselevels of NGF in a comparable biological sample, may be beneficial indiagnosing a disease or disorder associated with NGF.

Another embodiment of the invention provides a diagnostic or screeningassay to assist in diagnosis of diseases or disorders associated withNGF in patients exhibiting symptoms of an NGF associated disease ordisorder identified herein, comprising assaying the level of NGFexpression in a biological sample from said patient using apost-translationally modified anti-NGF antibody or binding fragmentthereof. The anti-NGF antibody or binding fragment thereof may bepost-translationally modified to include a detectable moiety such as setforth previously in the disclosure.

The NGF level in the biological sample is determined using a modifiedanti-NGF antibody or binding fragment thereof as set forth herein, andcomparing the level of NGF in the biological sample against a standardlevel of NGF (e.g., the level in normal biological samples). The skilledclinician would understand that some variability may exist betweennormal biological samples, and would take that into consideration whenevaluating results. In one embodiment of the invention, the anti-NGFantibodies of the invention may be used to correlate NGF expressionlevels with a particular stage of cancerous development. One skilled inthe art would be able to measure NGF in numerous subjects in order toestablish ranges of NGF expression that correspond to clinically definedstages of cancerous development. These ranges will allow the skilledpractitioner to measure NGF in a subject diagnosed with a cancer andcorrelate the levels in each subject with a range that corresponds to astage of said cancer. One skilled in the art would understand that bymeasuring NGF in the patient at different intervals, the progression ofthe cancer can be determined.

The above-recited assay may also be useful in monitoring a disease ordisorder, where the level of NGF obtained in a biological sample from apatient believed to have a NGF associated disease or disorder iscompared with the level of NGF in prior biological samples from the samepatient, in order to ascertain whether the NGF level in said patient haschanged with, for example, a treatment regimen.

The invention is also directed to a method of in vivo imaging whichdetects the presence of cells which express NGF comprising administeringa diagnostically effective amount of a diagnostic composition. Said invivo imaging is useful for the detection or imaging of NGF expressingtumors or metastases, for example, and can be useful as part of aplanning regimen for the design of an effective cancer treatmentprotocol. The treatment protocol may include, for example, one or moreof radiation, chemotherapy, cytokine therapy, gene therapy, and antibodytherapy, as well as an anti-NGF antibody or fragment thereof.

The present invention further provides for a kit for detecting bindingof an anti-NGF antibody of the invention to NGF. In particular, the kitmay be used to detect the presence of a NGF specifically reactive withan anti-NGF antibody of the invention or an immunoreactive fragmentthereof. The kit may also include an antibody bound to a substrate, asecondary antibody reactive with the antigen and a reagent for detectinga reaction of the secondary antibody with the antigen. Such a kit may bean ELISA kit and can comprise the substrate, primary and secondaryantibodies when appropriate, and any other necessary reagents such asdetectable moieties, enzyme substrates, and color reagents, for exampleas described herein. The diagnostic kit may also be in the form of animmunoblot kit.

A skilled clinician would understand that a biological sample includes,but is not limited to, sera, plasma, urine, saliva, mucous, pleuralfluid, synovial fluid and spinal fluid.

Any suitable combination of these active agents isalso contemplated.

A “pharmaceutical excipient” or a “pharmaceutically acceptableexcipient” is a carrier, usually a liquid, in which an activetherapeutic agent is formulated. In one embodiment of the invention, theactive therapeutic agent is a chimeric or humanized antibody fortreatment or prevention of pain and pain associated conditions describedherein, or one or more fragments thereof. The excipient generally doesnot provide any pharmacological activity to the formulation, though itmay provide chemical and/or biological stability, and releasecharacteristics. Exemplary formulations can be found, for example, inRemington's Pharmaceutical Sciences, 19th Ed., Grennaro, A., Ed., 1995which is incorporated by reference.

As used herein “pharmaceutically acceptable carrier” or “excipient”includes any and all solvents, dispersion media, coatings, antibacterialand antifungal agents, isotonic and absorption delaying agents that arephysiologically compatible. In one embodiment, the carrier is suitablefor parenteral administration. Alternatively, the carrier can besuitable for intravenous, intraperitoneal, intramuscular, or sublingualadministration. Pharmaceutically acceptable carriers include sterileaqueous solutions or dispersions and sterile powders for theextemporaneous preparation of sterile injectable solutions ordispersions. The use of such media and agents for pharmaceuticallyactive substances is well known in the art. Except insofar as anyconventional media or agent is incompatible with the active compound,use thereof in the pharmaceutical compositions of the invention iscontemplated. Supplementary active compounds can also be incorporatedinto the compositions.

Pharmaceutical compositions typically must be sterile and stable underthe conditions of manufacture and storage. The invention contemplatesthat the pharmaceutical composition is present in lyophilized form. Thecomposition can be formulated as a solution, microemulsion, liposome, orother ordered structure suitable to high drug concentration. The carriercan be a solvent or dispersion medium containing, for example, water,ethanol, polyol (for example, glycerol, propylene glycol, and liquidpolyethylene glycol), and suitable mixtures thereof. The inventionfurther contemplates the inclusion of a stabilizer in the pharmaceuticalcomposition. The proper fluidity can be maintained, for example, by theuse of a coating such as lecithin, by the maintenance of the requiredparticle size in the case of dispersion and by the use of surfactants.

In many cases, it will be preferable to include isotonic agents, forexample, sugars, polyalcohols such as mannitol, sorbitol, or sodiumchloride in the composition. Prolonged absorption of the injectablecompositions can be brought about by including in the composition anagent which delays absorption, for example, monostearate salts andgelatin. Moreover, the alkaline polypeptide can be formulated in a timerelease formulation, for example in a composition which includes a slowrelease polymer. The active compounds can be prepared with carriers thatwill protect the compound against rapid release, such as a controlledrelease formulation, including implants and microencapsulated deliverysystems. Biodegradable, biocompatible polymers can be used, such asethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen,polyorthoesters, polylactic acid and polylactic, polyglycolic copolymers(PLG). Many methods for the preparation of such formulations are knownto those skilled in the art.

For each of the recited embodiments, the compounds can be administeredby a variety of dosage forms. Any biologically-acceptable dosage formknown to persons of ordinary skill in the art, and combinations thereof,are contemplated. Examples of such dosage forms include, withoutlimitation, reconstitutable powders, elixirs, liquids, solutions,suspensions, emulsions, powders, granules, particles, microparticles,dispersible granules, cachets, inhalants, aerosol inhalants, patches,particle inhalants, implants, depot implants, injectables (includingsubcutaneous, intramuscular, intravenous, and intradermal), infusions,and combinations thereof.

EXAMPLES Example 1 Preparation of Antibodies that Bind NGF

By using the antibody selection protocol described herein, one cangenerate an extensive panel of antibodies.

Immunization Strategy

Rabbits were immunized with huNGF (R&D Systems, Minneapolis, Minn.).Immunization consisted of a first subcutaneous (sc) injection of 100 μgin complete Freund's adjuvant (CFA) (Sigma) followed by two boosts, twoweeks apart, of 50 μg each in incomplete Freund's adjuvant (IFA)(Sigma). Animals were bled on day 55, and serum titers were determinedby ELISA (antigen recognition) and by non-radioactive proliferationassay (Promega) using the T1165 cell line.

Antibody Selection Titer Assessment

To identify and characterize antibodies that bind to human NGF, antibodycontaining solutions were tested by ELISA. Briefly, neutravidin coatedplates (Thermo Scientific), were blocked with ELISA buffer (0.1 mg/mLBSA, 1×PBS pH 7.4, 0.002% Tween 20 and 0.005% sodium azide) for 1 hr atroom temperature. The plates were then coated with a 1 μg/mLbiotinylated B-NGF solution in ELISA buffer for 1 hour at roomtemperature. This was followed by a wash step (3× using PBS plus 0.05%Tween 20) and a second block with ELISA buffer. The recombinantantibodies were then added onto the plates and incubated for 1 hour atroom temperature and then washed 3× with PBS/Tween solution. Fordevelopment, an anti-rabbit Fc-HRP (1:5000 dilution in ELISA buffer) wasadded onto the wells and incubated for 45 min at RT. After a 3× washstep with PBS/Tween solution, the plate was developed using TMBsubstrate for 3 minutes, stopped using 0.5M HCl and read at 450 nm.

Functional Titer Assessment

To test for the ability of NGF antibodies to block NGF-dependent cellproliferation, we used TF-1 cells (Chevalier et al. Expression andfunctionality of the trkA proto-oncogene product/NGF receptor inundifferentiated hematopoietic cells. Blood (1994) vol. 83 (6) pp.1479-85). Briefly, TF-1 cells were maintained in 10% FBS cRPMI media(“complete media”) supplemented with rhuGM-CSF. On the day of the assay,the antibodies were serially diluted in complete media in a round bottom96 well plate. B-NGF (R&D systems) was concomitantly added and theresultant antibody/B-NGF mixture was incubated at 37° C. for 1 hr. Whilethe Ab and B-NGF mixture was incubating, TF-1 cells were washed 3× withcomplete media, counted and plated in a flat bottom 96 well plate using25,000 cells per well in a 50 μL volume. After 1 hour incubation theNGF-Antibody mixtures were added onto the cells and the plates wereincubated for 48 hrs at 37° C. in a humidified 5% CO2 incubator. Cellproliferation was measured using the “CellTiter” aqueous one solutioncell proliferation assay (Promega) according to the manufacturer'sinstructions. The dependency of the signals on the concentration ofantibody was analyzed, and IC50 values were calculated using theGraphPad Prism program.

Tissue Harvesting

Once acceptable titers were established, the rabbit(s) were sacrificed.Spleen, lymph nodes, and whole blood were harvested and processed asfollows:

Spleen and lymph nodes were processed into a single cell suspension bydisassociating the tissue and pushing through sterile wire mesh at 70 μm(Fisher) with a plunger of a 20 cc syringe. Cells were collected in PBS.Cells were washed twice by centrifugation. After the last wash, celldensity was determined by trypan blue. Cells were centrifuged at 1500rpm for 10 minutes; the supernatant was discarded. Cells wereresuspended in the appropriate volume of 10% dimethyl sulfoxide (DMSO,Sigma) in FBS (Hyclone) and dispensed at 1 ml/vial. Vials were stored at−70° C. in a slow freezing chamber for 24 hours and stored in liquidnitrogen.

Peripheral blood mononuclear cells (PBMCs) were isolated by mixing wholeblood with equal parts of the low glucose medium described above withoutFBS. 35 ml of the whole blood mixture was carefully layered onto 8 ml ofLympholyte Rabbit (Cedarlane) into a 45 ml conical tube (Corning) andcentrifuged 30 minutes at 2500 rpm at room temperature without brakes.After centrifugation, the PBMC layers were carefully removed using aglass Pasteur pipette (VWR), combined, and placed into a clean 50 mlvial. Cells were washed twice with the modified medium described aboveby centrifugation at 1500 rpm for 10 minutes at room temperature, andcell density was determined by trypan blue staining. After the lastwash, cells were resuspended in an appropriate volume of 10% DMSO/FBSmedium and frozen as described above.

B Cell Culture

On the day of setting up B cell culture, PBMC, splenocyte, or lymph nodevials were thawed for use. Vials were removed from LN2 tank and placedin a 37° C. water bath until thawed. Contents of vials were transferredinto 15 ml conical centrifuge tube (Corning) and 10 ml of modified RPMIdescribed above was slowly added to the tube. Cells were centrifuged for5 minutes at 1.5K rpm, and the supernatant was discarded. Cells wereresuspended in 10 ml of fresh media. Cell density and viability wasdetermined by trypan blue. Cells were washed again and resuspended at1E07 cells/80 μL medium. Biotinylated huNGF (B huNGF) was added to thecell suspension at the final concentration of 3 ug/mL and incubated for30 minutes at 4° C. Unbound B huNGF was removed with two 10 ml washes ofphosphate-buffered (PBF):Ca/Mg free PBS (Hyclone), 2 mM ethylenediaminetetraacetic acid (EDTA), 0.5% bovine serum albumin (BSA) (Sigma-biotinfree). After the second wash, cells were resuspended at 1E07 cells/80 μlPBF. 20 μl of MACS® streptavidin beads (Milteni)/10E7 cells were addedto the cell suspension. Cells were incubated at 4° C. for 15 minutes.Cells were washed once with 2 ml of PBF/10E7 cells. After washing, thecells were resuspended at 1E08 cells/500 μl of PBF and set aside. AMACS® MS column (Milteni) was pre-rinsed with 500 ml of PBF on amagnetic stand (Milteni). Cell suspension was applied to the columnthrough a pre-filter, and unbound fraction was collected. The column waswashed with 1.5 ml of PBF buffer. The column was removed from the magnetstand and placed onto a clean, sterile 5 ml Polypropylene Falcon tube. 1ml of PBF buffer was added to the top of the column, and positiveselected cells were collected. The yield and viability of positive andnegative cell fraction was determined by trypan blue staining Positiveselection yielded an average of 1% of the starting cell concentration.

A pilot cell screen was established to provide information on seedinglevels for the culture. Plates were seeded at 10, 25, 50, 100, or 200enriched B cells/well. In addition, each well contained 50K cells/wellof irradiated EL-4.B5 cells (5,000 Rads) and an appropriate level ofactivated rabbit T cell supernatant (See U.S. Patent ApplicationPublication No. 20070269868)(ranging from 1-5% depending on preparation)in high glucose modified RPMI medium at a final volume of 250 μl/well.Cultures were incubated for 5 to 7 days at 37° C. in 4% CO2.

Identification of Selective Antibody Secreting B Cells

Cultures were tested for antigen recognition and functional activitybetween days 5 and 7.

Antigen Recognition Screening

The ELISA format used is as described above except 50 μl of supernatantfrom the B cell cultures (BCC) wells was used as the source of theantibody. The conditioned medium was transferred to antigen-coatedplates. After positive wells were identified, the supernatant wasremoved and transferred to a 96-well master plate(s). The originalculture plates were then frozen by removing all the supernatant except40 μl/well and adding 60 μl/well of 16% DMSO in FBS. Plates were wrappedin paper towels to slow freezing and frozen after the addition of 10%DMSO at −70° C.

Functional Activity Screening

To test for the ability of NGF antibodies to block NGF-dependent cellproliferation, we used TF-1 cells (Chevalier et al. Expression andfunctionality of the trkA proto-oncogene product/NGF receptor inundifferentiated hematopoietic cells. Blood (1994) vol. 83 (6) pp.1479-85). Briefly, TF-1 cells were maintained in 10% FBS cRPMI media(“complete media”) supplemented with rhuGM-CSF. On the day of the assay,the antibodies were serially diluted in complete media in a round bottom96 well plate. B-NGF (R&D systems) was concomitantly added and theresultant antibody/B-NGF mixture was incubated at 37° C. for 1 hr. Whilethe Ab and B-NGF mixture was incubating, TF-1 cells were washed 3× withcomplete media, counted and plated in a flat bottom 96 well plate using25,000 cells per well in a 50 μL volume. After 1 hour incubation theNGF-Antibody mixtures were added onto the cells and the plates wereincubated for 48 hrs at 37° C. in a humidified 5% CO2 incubator. Cellproliferation was measured using the “CellTiter” aqueous one solutioncell proliferation assay (Promega) according to the manufacturer'sinstructions. The dependency of the signals on the concentration ofantibody was analyzed, and IC50 values were calculated using theGraphPad Prism program.

B Cell Recovery

Plates containing wells of interest were removed from −70° C., and thecells from each well were recovered with 5-200 μl washes of medium/well.The washes were pooled in a 1.5 ml sterile centrifuge tube, and cellswere pelleted for 2 minutes at 1500 rpm.

The tube was inverted, the spin repeated, and the supernatant carefullyremoved. Cells were resuspended in 100 μl/tube of medium. 100 μlbiotinylated NGF coated streptavidin M280 dynabeads (Invitrogen) and 16μl of goat anti-rabbit H&L IgG-FITC diluted 1:100 in medium was added tothe cell suspension.

20 μl of cell/beads/FITC suspension was removed, and 5 μl droplets wereprepared on a glass slide (Corning) previously treated with Sigmacote(Sigma), 35 to 40 droplets/slide. An impermeable barrier of paraffin oil(JT Baker) was added to submerge the droplets, and the slide wasincubated for 90 minutes at 37° C., 4% CO2 in the dark.

Specific B cells that produce antibody can be identified by thefluorescent ring around them due to antibody secretion, recognition ofthe bead-associated biotinylated antigen, and subsequent detection bythe fluorescent-IgG detection reagent. Once a cell of interest wasidentified, the cell in the center of the fluorescent ring was recoveredvia a micromanipulator (Eppendorf). The single cell synthesizing andexporting the antibody was transferred into a 250 μl microcentrifugetube and placed in dry ice. After recovering all cells of interest,these were transferred to −70° C. for long-term storage.

Isolation of Antibody Sequences from Antigen-Specific B Cell

Antibody sequences were recovered using a combined RT-PCR based methodfrom a single isolated B-cell or an antigenic specific B cell isolatedfrom the clonal B cell population. Primers are designed to anneal inconserved and constant regions of the target immunoglobulin genes (heavyand light), such as rabbit immunoglobulin sequences, and a two-stepnested PCR recovery step is used to obtain the antibody sequence.Amplicons from each well are analyzed for recovery and size integrity.The resulting fragments are then digested with AluI to fingerprint thesequence clonality. Identical sequences display a common fragmentationpattern in their electrophoretic analysis. The original heavy and lightchain amplicon fragments are then restriction enzyme digested withHindIII and XhoI or HindIII and BsiwI to prepare the respective piecesof DNA for cloning. The resulting digestions are then ligated into anexpression vector and transformed into bacteria for plasmid propagationand production. Colonies are selected for sequence characterization.

Recombinant Production of Monoclonal Antibody of Desired AntigenSpecificity and/or Functional Properties

Correct full-length antibody sequences for each well containing a singlemonoclonal antibody are established and miniprep DNA is prepared usingQiagen solid-phase methodology. This DNA is then used to transfectmammalian cells to produce recombinant full-length antibody. Eitherantibody containing supernatants or protein-A affinity purifiedantibodies are tested for antigen recognition and functional propertiesto confirm the original characteristics are found in the recombinantantibody protein.

Antigen Specific ELISA

To identify and characterize antibodies and Fab fragments that bind tohuman NGF, antibody- and Fab-containing solutions were tested by ELISA.Briefly, neutravidin coated plates (Thermo Scientific), were blockedwith ELISA buffer (0.1 mg/mL BSA, 1×PBS pH 7.4, 0.002% Tween 20 and0.005% sodium azide) for 1 hr at room temperature. The plates were thencoated with a 1 μg/mL biotinylated B-NGF solution in ELISA buffer for 1hour at room temperature. This was followed by a wash step (3× using PBSplus 0.05% Tween 20) and a second block with ELISA buffer. Therecombinant antibodies or Fabs were then added onto the plates andincubated for 1 hour at room temperature and then washed 3× withPBS/Tween solution. For development, an anti-human Fc-HRP or ananti-human Fab-fragment HRP (1:5000 dilution in ELISA buffer) was addedonto the wells and incubated for 45 min at RT. After a 3× wash step withPBS/Tween solution, the plate was developed using TMB substrate for 3minutes, stopped using 0.5M HCl, and read at 450 nm.

Results: FIGS. 24-40 demonstrate that anti-NGF antibodies Ab1-Ab21 bindto NGF. Furthermore, FIGS. 28 and 29 demonstrate that Fab antibodyfragments Fab1 and Fab2 bind to NGF.

Functional Activity Screening

To test for the ability of NGF antibodies to block NGF-dependent andTrkA receptor-mediated cell proliferation activity, we used TF-1 cells(Chevalier et al. Expression and functionality of the trkAproto-oncogene product/NGF receptor in undifferentiated hematopoieticcells. Blood (1994) vol. 83 (6) pp. 1479-85). Briefly, TF-1 cells weremaintained in 10% FBS cRPMI media (“complete media”) supplemented withrhuGM-CSF. On the day of the assay, the antibodies were serially dilutedin complete media in a round bottom 96 well plate. B-NGF (R&D systems)was concomitantly added and the resultant antibody/B-NGF mixture wasincubated at 37° C. for 1 hr. While the Ab and B-NGF mixture wasincubating, TF-1 cells were washed 3× with complete media, counted andplated in a flat bottom 96 well plate using 25,000 cells per well in a50 μL volume. After 1 hour incubation the NGF-Antibody mixtures wereadded onto the cells and the plates were incubated for 48 hrs at 37° C.in a humidified 5% CO2 incubator. Cell proliferation was measured usingthe “CellTiter” aqueous one solution cell proliferation assay (Promega)according to the manufacturer's instructions. The dependency of thesignals on the concentration of antibody was analyzed, and IC50 valueswere calculated using the GraphPad Prism program.

Results: FIGS. 41-52 demonstrate that anti-NGF antibodies Ab1-Ab20inhibit the proliferation of TF-1 cells. Furthermore, FIG. 44demonstrates that Fab antibody fragments also inhibit the proliferationof TF-1 cells. These Fab antibody fragments were produced by: 1.) Pichiapastoris expression of Fab2; and 2.) enzymatic digestion of Ab21produced in Pichia pastoris (Fab1).

Example 2 Enzymatic Production of Fab Fragments

Papain digestions were conducted using immobilized papain(Thermo/Pierce) as per manufacturer's instructions. Briefly, purifiedantibodies were incubated in a cystein/HCl-containing buffer withimmobilized papain at 37° C. with gentle rocking. The digestion wasmonitored by taking an aliquot and analyzing using SDS-PAGE for cleavageof the heavy chain. To stop the reaction, the immobilized papain wasspun out and washed using 50 mM Tris pH 7.5 and filtered. Undigestedfull length antibody and Fc fragments were removed by using aMabSelectSure (GE) column.

Example 3 Yeast Cell Expression

Antibody genes: Genes were cloned and constructed that directed thesynthesis of a chimeric or humanized rabbit monoclonal antibody.

Methods

Construction of Pichia pastoris Expression Vectors for Heavy and LightChain Antibodies.

The light and heavy chain fragments (chimera or humanized) werecommercially synthesized and subcloned into a pGAP expression vector.The pGAP expression vector uses the GAP promoter to drive expression ofthe immunoglobulin chain and the human serum albumin (HAS) leadersequence for export. In addition, this vector contains common elementssuch as a bacterial origin of replication, and a copy of the Sh ble genewhich confers resistance to the antibiotic Zeocin™ (phleomycin). Zeocin™provides a means of selection for strains that contain the desiredexpression vector integrated into their genome.

Transformation of Expression Vectors into Haploid Met1 and Lys3 HostStrains of Pichia pastoris

All methods used for transformation of haploid P. pastoris strains andmanipulation of the P. pastoris sexual cycle were done as described inPichia Protocols (Methods in Molecular Biology Higgings, D R, and Cregg,J M, Eds. 1998. Humana Press, Totowa, N.J.). Prior to transformationeach vector was linearized within the GAP promoter sequences to directthe integration of the vector into the GAP promoter locus of the P.pastoris genome. Haploid strains were transfected using electroporationand successful transformants were selected on YPD Zeocin™ plates andthen cultured in 96-well plates for two days. Haploid strains were matedand selected for their ability to grow in the absence of the auxotrophmarkers (i.e., Lys and Met). Diploid strains were then selected fortheir ability to express either full length or Fab antibody fragmentsusing a ForteBio Octet system fitted with Protein A biosensors tomonitor expression.

Example 4 Expression of Ab21 and Fab2 in Pichia pastoris

Two Pichia strains for expression of either full length Ab21 or Fab2antibody fragment were made. For both the full length or the Fabexpressing strains, haploids strains were created and subsequentlymated. One haploid strain expressed full length light sequences for Ab21and another haploid strain expressed either the full length Ab21 or atruncated form of heavy chain to express an Fab fragment (e.g., Fab2).Each diploid strain was used to generate a research cell bank and usedfor expression in a bioreactor.

First an inoculum was expanded using the research cell bank using mediumcomprised of the following nutrients (% w/v): yeast extract 3%,anhydrous dextrose 4%, YNB 1.34%, 0.004% Biotin with 100 mM potassiumphosphate. The culture was expanded for approximately 24 hours in ashaking incubator at 30° C. and 300 rpm to generate the inoculum for thefermenters. A 10% inoculum was then added to Labfors 2.5 L workingvolume vessels containing sterile growth medium. The growth medium forthe full length Ab21 was comprised of the following nutrients: potassiumsulfate 18.2 g/L, ammonium phosphate monobasic 36.4 g/L, potassiumphosphate dibasic 12.8 g/L, magnesium sulfate heptahydrate 3.72 g/L,sodium citrate dihydrate 10 g/L, glycerol 40 g/L, yeast extract 30 g/L,PTM1 trace metals 4.35 mL/L, and antifoam 204 1.67 mL/L. The PTM1 tracemetal solution was comprised of the following components: cupric sulfatepentahydrate 6 g/L, sodium iodide 0.08 g/L, manganese sulfate hydrate 3g/L, sodium molybdate dihyrate 0.2 g/L, boric acid 0.02 g/L, cobaltchloride 0.5 g/L, zinc chloride 20 g/L, ferrous sulfate heptahydrate 65g/L, biotin 0.2 g/L, and sulfuric acid 5 mL/L.

The growth medium for the Fab2 fragment was comprised of the followingnutrients: potassium sulfate 10.92 g/L, ammonium phosphate monobasic21.84 g/L, potassium phosphate dibasic 7.68 g/L, magnesium sulfateheptahydrate 3.72 g/L, sodium citrate dihydrate 10 g/L, glycerol 40 g/L,yeast extract 30 g/L, PTM1 trace metal solution 2.61 mL/L, and antifoam204 1.67 mL/L. The PTM1 trace metal solution was comprised of thefollowing components: cupric sulfate pentahydrate 6 g/L, sodium iodide0.08 g/L, manganese sulfate hydrate 3 g/L, sodium molybdate dihyrate 0.2g/L, boric acid 0.02 g/L, cobalt chloride 0.5 g/L, zinc chloride 20 g/L,ferrous sulfate heptahydrate 65 g/L, biotin 0.2 g/L, and sulfuric acid 5mL/L. Both proteins were expressed under similar conditions. Briefly,the bioreactor process control parameters were set as follows: Agitation1000 rpm, airflow 1.35 standard liter per minute, temperature 28° C. andpH was controlled at six using ammonium hydroxide. No oxygensupplementation was provided.

The fermentation cultures were grown for approximately 12 to 16 hoursuntil the initial glycerol was consumed as denoted by a dissolved oxygenspike. The cultures were starved for approximately three hours after thedissolved oxygen spike. After this starvation period, a bolus additionof ethanol was added to the reactor to reach 1% ethanol (w/v). Thefermentation cultures were allowed to equilibrate for 15 to 30 minutes.Feed addition was initiated 30 minutes post-ethanol bolus and set at aconstant rate of 1 mL/min for 40 minutes, then the feed pump wascontrolled by an ethanol sensor keeping the concentration of ethanol at1% for the remainder of the run. The feed was comprised of the followingcomponents: yeast extract 50 g/L, dextrose 500 g/L, magnesium sulfateheptahydrate 3 g/L, and PTM1 trace metals 12 mL/L. For fermentation ofthe full length Ab21, sodium citrate dihydrate (0.5 g/L) was also addedto the feed. The total fermentation time was approximately 90 hours.

Example 5 Inhibition of NGF-p75 Interactions

NGF is reported to interact with two receptors on the cell surface: TrkAand p75. A biolayer interferometry assay via the “Octet” was used tocharacterize the ability of anti-NGF antibodies to inhibit NGF-p75interactions. Briefly, streptavidin (SA) sensors were pre-wetted in 1×kinetics buffer (1×PBS pH 7.4, 0.002% Tween 20, 0.005% sodium azide and0.1 mg/mL BSA). A baseline was obtained using again 1× kinetics buffer,followed by binding of the biotinylated antibody being tested andanother short baseline in 1× kinetics buffer. NGF (1 μg/mL) was loadednext and the sensor was then transferred onto 1× kinetics buffer. Afterloading of NGF onto the antibody, on one sensor, all possible sites ofNGF were blocked using an un-labeled solution of the biotinylatedantibody at 5 μg/mL. As control, a parallel sensor was submerged into 1×kinetics buffer during this second blocking step. Both sensors were thenexposed to a solution containing p75 (1.2 μg/mL). The ability of anantibody to block NGF-p75 interactions was then characterized bymonitoring the increase in signal when antibody-immobilized NGF wasexposed to soluble p75.

Results: FIGS. 53 and 54 demonstrates that anti-NGF antibodies Ab3, Ab4,Ab15, and Ab16 do not inhibit binding of NGF to p75, while FIG. 55demonstrates that antibody Ab5 inhibits binding of NGF to p75.

Example 6 Neurite PC12 Assay

The ability of anti-NGF antibodies to block NGF signaling mediatedthrough the p75 and TrkA receptors was measured in vitro using a ratadrenal medulla cell line, PC12. PC12 cells express both p75 and TrkAreceptors on their cell surface (Urdiales et al. Cell cyclephase-specific surface expression of nerve growth factor receptors TrkAand p75(NTR). J Neurosci (1998) vol. 18 (17) pp. 6767-75); (Greene andTischler. Establishment of a noradrenergic clonal line of rat adrenalpheochromocytoma cells which respond to nerve growth factor. Proc NatlAcad Sci USA (1976) vol. 73 (7) pp. 2424-8). Briefly, PC12 cells weremaintained in culture using 15% FBS RPMI and grown on a collagenI-coated flask for 48 hours before priming. The cells were then ‘primed’for 72 hours by exposing them to 100 ng/mL NGF in differentiation media(1% horse serum RPMI). On the day of the assay, the cells were harvestedwith a cell scraper, resuspended, rinsed in differentiation media(without NGF) and plated onto a collagen I-coated 24-well plate. Thefinal concentration of NGF in the assay was 100 ng/mL. The antibodiesbeing tested were pre-incubated with the NGF at different molar ratios(from 10× to 0.1×) for 1 hour in differentiation media prior to addingthem onto the PC-12 cells. On day 3, the media was gently removed andantibody-NGF mixtures were replaced. On day 10, the wells were observedunder a microscope and representative fields were digitized using a 10×magnification lens.

Results: FIGS. 56-69 and FIGS. 78 and 79 demonstrate that anti-NGFantibodies Ab1-Ab3, Ab5-Ab11, Ab13, Ab15, Ab16, and Ab17-Ab19 inhibitthe outgrowth of PC-12 neurite cells at increasing concentrations. Itcan be seen that antibodies Ab3, Ably and Ab16, when assayed at the sameantibody concentrations as the other tested anti-NGF antibodies (thosethan antagonize the interaction of NGF with both Trka and p75), showedsignificantly less inhibition of the outgrowth of PC-12 neurite cells.This difference is believed to be attributable to the fact that Ab3,Ab15 and Ab16, all inhibit TrkA/NGF interactions and not NGF/p75interactions, whereas the remaining tested antibodies inhibit theinteraction of NGF with both TrkA and p75.

Example 7 Modulation of Pain Assessed by Gait Analysis

To assess the effect of anti-NGF agents (full length and Fab fragments)in their ability to modulate pain, a PGPS (peptidoglycanpolysaccharide)-induced arthritis model was used. Briefly, male Lewisrats were injected with a solution of PGPS into their right ankle on day(−)17. One day later, ankles were evaluated for an inflammatory responseto the PGPS injection and non-responders were eliminated. Responderswere allowed to recover for seventeen days before an IV tail veinreactivation with PGPS.

Full-length antibodies were dosed once, either 2 hours or the nightbefore reactivation. Fab fragments were administered once a day with thefirst dose administered two hours prior to reactivation. Gait analysiswas performed by applying ink to the ventral surface of the foot anddocumenting weight bearing during movement (footprints) across paper.The rear feet of the rats were placed in blue colored ink, and black inkwas applied to the dorsal side of the foot on the suspected painful leg.Rats were placed on paper and allowed to walk. Gaits were scored asfollows: 0=normal, equal ink staining on both feet; 1=slight limp, toestaining evident and some heel staining; 2=limping, toes only staining;3=dragging/carrying leg, black drag marks from dorsal side of footpresent; 4=carrying leg, no staining from painful leg.

To assess the effect of anti-NGF agents (full length and Fab fragments)in their ability to modulate pain, a PGPS (peptidoglycanpolysaccharide)-induced arthritis model was used. Briefly, male Lewisrats were injected with a solution of PGPS into their right ankle on day(−)17. One day later, ankles were evaluated for an inflammatory responseto the PGPS injection and non-responders were eliminated. Responderswere allowed to recover for seventeen days before an IV tail veinreactivation with PGPS. On day 2 post-reactivation, animals were testedby gait for pain and randomized based on their pain response. Theanimals were then dosed via IV injection receiving 5 mg/kg of either anegative control antibody or a test agent.

Full-length antibodies and Fab fragments were dosed once, either 2 hoursor the night before reactivation. Gait analysis was performed byapplying ink to the ventral surface of the foot and documenting weightbearing during movement (footprints) across paper. The rear feet of therats were placed in blue colored ink, and black ink was applied to thedorsal side of the foot on the suspected painful leg. Rats were placedon paper and allowed to walk.
